Version 0.2.0
=============

* Redundant if checker - check for if (x) then true else false

* DeprecatedJavaChecker - check usage of @Deprecated as a java annotation
* Empty class checker - warns if an empty class is used
* underscore import checker - warns on use of wildcard imports
* Lowercase pattern matcher checker - warns on use of a lowercase pattern match case x => foo, which can cause unexpected behaviour
* duplicated string literals in a file checker.
* Import grouping checker

Also:

* Upgrade to Scala 2.9.2
* An SBT plugin, which generates checkstyle type report xml for jenkins
* Correct handling of file encoding in the maven and Eclipse plugins
* The maven plugin can optionally generate checkstyle type report xml for jenkins
* Corrections to the import checker, to cope with import selectors
